I have had three instances recently where I was inspecting my sales receipt and found that I was charged either more than the posted price, more than the posted sales price or extra for something I didn’t even buy. In each case, I marched back in the store, went to customer service and got a refund.
All I am saying is…be careful. Check your receipt. Sales Clerks these days are either ignorant or thieves…in most cases…so be forewarned!
